Summary of content (21 pages)

PAGE 1
EPA (END POINT ADJUSTMENT) G (Landing Gear End Points) The RDS8000 allows you to adjust the “End Point”, or travel limit, for all flight channels. In most cases, (almost all cases in the past) the total servo throw for the landing gear function could not be set by the transmitter, because most retract servos are SWITCHED (non-proportional) servos. With these servos, mechanical adjustment was the only method available to ensure proper operation of the retracts.
PAGE 2
TRM (TRIM MEMORY) FLAPE (FLAPERONS) The RDS8000 offers the Trim Memory Function on all four of the flight control channels and the Flap Channel. Trim Memory for Elevator, Aileron, Throttle, and Rudder is input by the Digital Trim keys. It can also be set when you use the INC +/YES or DEC -/NO keys to input trim. The Flaperon function can be used to obtain two separate aileron channels with a servo in each wing.
PAGE 3
Press the (CH –) key to select P-F on the Channel indicator. ALARMS D/R-A(DUAL RATE ALARM) THROTTLE STICK HIGH The RDS8000 offers an “ALARM” function to warn you if you turn your transmitter on while a Dual Rate Switch is activated, and another to warn you if you turn the transmitter on while the Throttle Stick is in any position other than Full-Low throttle. TH-Hi! Will be displayed on the LCD screen until you place the Throttle stick in the full-low position.
PAGE 4
DELTA (ELEVONS) A>R (AILERON-RUDDER MIX) DELTA mix can be used in a flying-wing type model to provide ELEVON control, where the elevator and aileron functions are combined. The RDS8000 provides the capability to program your aircraft so that Aileron stick deflection will also cause the rudder servo to respond in the same direction, (right aileron=right rudder).
PAGE 5
V-TAIL (RUDDER-ELEVATOR MIX) T>E (THROTTLE-ELEVATOR MIX) The RDS8000 transmitter has the ability to control sailplanes or powered models that use a V-Tail control system. In these aircraft the two tail controls perform both as elevators and as rudders. Two servos and two channels (receiver channels #1 and #4 are required for V-Tail operation). The RDS8000 allows automatic adjustment of Elevator trim as you advance or retard the throttle stick.
PAGE 6
COMPENSATION MIXERS (C-Mix) The RDS8000 has two compensation mixers to handle advanced mixing needs. These are in addition to the predefined mixers. Now use the FUNCTION down key until you reach the (MAS 1:) screen. Next use the INC or DEC keys until the RU (rudder) is selected. This will be your Master channel. A Compensation Mixer allows one transmitter control input to affect two flight functions. A common mix would be Aileron to Rudder to achieve coordinated turns without moving the rudder stick.
PAGE 7
ELEVATOR-FLAP MIXING RUDDER-AILERON MIXING This function causes the flaps to deploy when the elevator control stick is moved up or down. It can be used with a separate flap servo with an output on the receivers channel #6 or as flaperons with two aileron servos on channel #2 and #6. This function is most commonly used for aerobatic models where deploying flaps (or flaperons) with elevator control make tighter corners on maneuvers such as the square loop.
PAGE 8
FLAP-ELEVATOR MIXING AL-DIF (AILERON DIFFERENTIAL) This feature is used when you deploy the flaps. Normally when you drop the flaps on an aircraft it will start to climb. Adding some down elevator will help reduce it. Adjustment is from (100) to (-100)%.
PAGE 9
L-DIF (LANDING DIFFERENTIAL) The L-DIF (landing differential) function enables the ailerons of a sailplane to be effective whenever both the left and right ailerons are raised when CROW or SPOILERON are used in landing. Typical thermal sailplanes require about twice as much up travel as down travel of the ailerons to produce a coordinated turn. The RDS8000 allows you to set the amount of differential aileron travel during the landing mode. To use L-DIF the SPOIR (Spoileron) function must be set to Active.
PAGE 10
OPTION MENU SCREEN STEP (TRIM STEP) In the advanced programming you have the ability to turn off unused programming screens with the OPTION MENU SCREEN. This is very useful and convenient when one of your models only requires some features. For example, one aircraft is used as a trainer and you do not need to use any C-MIX, CROW, AI-DIF, DELTA, V-TAIL, you can go to the OPT screen and turn them off so they will not display in the normal programming screens.
PAGE 11
DUAL ELEVATOR MIXING RDS8000 Transmitter - HELICOPTER Your RDS8000 offers DUAL ELEVATOR MIXING that allows you to use a separate servo for each elevator half. You use Channels 1 and 7 on the receiver for this feature. Activating the Dual Elevator feature will automatically disable your AUX-1 channel 7 switch and will allow channel 7 to be used with the elevator stick.

PITCH CURVES (FLIGHT MODES) Note that one of the small triangular indicators will be blinking to show that you should press the (CH+) key. Therefore, press the (CH+) key and the screen will change to read HELI with a flashing YES. The RDS8000 allows you to customize four distinct flight modes for each helicopter model. The four pitch curves (flight modes) available for each helicopter model are: N………………………….. Select 1…………………………... Select 2…………………………... Select 3…………………………...
PAGE 14
The pitch curve for each flight mode has five points that can be adjusted to suit your specific needs. Within each pitch curve these points are referred to as PH (high pitch), P3, P2, P1 and PL (low pitch). The range of values and default settings for each is shown below. To activate P3 and P1, press the YES key when in P3 or P1 screens. To set back to default, press both the YES and NO keys at the same time.
PAGE 15
THROTTLE CURVES (FLIGHT MODES) The throttle curve for each flight mode has five points that can be adjusted to suit your specific needs. Within each throttle curve these points are referred to as PH (high pitch) P3, P2, P1 and PL (low pitch). The range of values and default settings for each is shown below. To activate P3 and P1, press the YES key when in P3 or P1 screens. To set back to default, press both the YES and NO keys at the same time.
PAGE 16
REVOLUTION MIXING GYRO ADJUSTMENT The RDS8000 provides for setting Revolution Mixing for each of the four Flight Modes. Each Flight Mode has its own curve for adjusting tail rotor position in response to the throttle/collective stick movements. The default settings for RV.H (Revolution Mixing High Point), RV.M (Revolution Mixing Mid Point), and RV.L (Revolution Mixing Low Point) are as follows: The RDS8000 allows you to set the Gyro sensitivity of your helicopter’s gyro if it has that capability.
PAGE 17
TRM (TRIM MEMORY) DTM (DYNAMIC TRIM MEMORY) The RDS8000 offers the Trim Memory Function on all four flight control channels. Trim Memory for Elevator, Aileron, Throttle, and Rudder is input by the Digital Trim keys. It can also be set when you use the INC +/YES or DEC -/NO keys to input trim. Any trim that you set while your model is in flight by use of the Digital Trim keys will automatically be stored in memory for that specific channel and model.
PAGE 18
SWH (SWASH PLATE TYPE) CHANGING FLIGHT MODE 1 and 2 Switch Locations Your RDS8000 allows you to select the SWH (Swash) mode of operating the main rotor pitch, which is controlled by the Swash Plate moving up or down. When the Swash Mode is selected, the outputs of the Elevator, Aileron and Pitch servos are mixed to control the pitch of the helicopter's main rotor. Cyclic, Collective, Pitch Mixing (CCPM) can only be used on a helicopter that is designed for CCPM.
